Didactic bases of teaching "Physics of atomic and nuclear structure" in continuous physics education

The development of atomic and nuclear physics, the efficient use of nuclear energy plays an important role in the international arena. The structure of the atom and the nucleus, the training of internationally advanced personnel to improve the use of its energy is a topical issue today. The role of atomic and nuclear physics in education, science and industry in our country is wide. However, taking into account the fact that the introduction of modern and new areas of nuclear physics, such as radiation physics, deformed nucleus physics, into the system of continuing education will further increase the efficiency of specialists trained in this field.

Microscopic study of nuclear structure dynamics of neutron-deficient even–even 100–110Cd isotopes within the framework of projected shell model

We have studied the deformation systematics of [Formula: see text] and [Formula: see text] values, yrast spectra, band structure and backbending phenomena in the neutron-deficient even–even [Formula: see text]Cd isotopes within the projected shell model (PSM) framework. The observations of the systematics of [Formula: see text] and [Formula: see text] values for [Formula: see text]Cd isotopes are well reproduced in present calculations. Our observations show that, as we move from [Formula: see text]Cd to [Formula: see text]Cd, the deformation increases and then it reduces up to [Formula: see text]Cd. This gives us a confirmation that [Formula: see text]Cd is the most deformed nucleus in this set of isotopic mass chain. The backbending phenomena is also observed in these isotopes, which can be related to the crossing of ground band (g-band) by 2-quasiparticle (qp) bands or s-bands. The pseudomagic character of [Formula: see text]Cd has also been observed.

SPECTROSCOPY IN A ROTATING DEFORMED NUCLEUS

Recent advances in the physics of nuclei at high spin are presented. In particular the new phenomena observed by the latest generation of γ-rays spectrometers are discussed. An overview of experimental and theoretical treatment of "backbending·'' effect, quasiparticle alignment and band crossing is described in more detail. The outlines of the Cranked Shell Model, which is a successful framework for the interpretation of experimental data, are also reported.

Resonance width for a particle–core coupling model with a square-well potential

We derive a compact formula for the width of a multi-channel resonance state. To this end, we use a deformed square-well potential and solve the coupled-channels equations. We obtain the $S$-matrix in the Breit–Wigner form, from which partial widths can be extracted. We apply the resultant formula to a deformed nucleus and discuss the behavior of partial width for an $s$-wave channel.
